WINDMILL.

SPECIFICATI DN forming part of Letters Patent No. 298,570, dated May 13, 1884.

(No model.)

To ctZZ whom it may concern:

Be it known that I, J AMES B. Fosrnn, of Parsons, Labette county, Kansas, have invented anew and Improved \V indmill, of which the following is a full, clear, and exact description.

The invention consists of the several combinations of parts and their construction, substantially as hereinafter described, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a sectional elevation of my improved wind-wheel, together with pumping and automatic starting and stopping apparatus to set the wheel in motion when the water is low and to stop it when the tank is full. Fig. 2 is a horizontal section of the wheel. Fig. 3 is a detail of the fan-shifting apparatus in side elevation,with some parts in section. Fig. 4 is a plan view of the cam device for controlling the wheel, andsection of the vertical shaft of the wheel. Fig. 5 is a section of Fig. 3 on the line a w, and Fig.6 is a side elevation of one of the fans.

On the upper end of a vertical shaft, a, arranged in suitable bearings in the beams b c d of any suitable tower, I arrange a horizontal wheel consisting of hub 0, arms f, and rim g, suitably connected together and stayed by braces h, extending from the outer rim, 9, to the upper ends of the hub e. To each alternate arm f, I apply a fan, 2', connecting said fans to the arms by boxes or bearings j k, allowing the fans to turn freely on the arms. These boxes are connected to the fans a little out of the center, making them a little wider one side of the arms than the other, and the boxes 7c have a trailing arm, Z, on the wider sides of the fans, which sides turn down readily into the wind when said fans come into the position for taking the wind. These arms Z turn the fans edgewise to the wind and hold them in that position for returning to the position for taking the wind by running up the cam on and along the horizontal plate n at the top of the cam. At the front, where the fan takes the wind, the arms Z descend the incline o,

. end on the collars.

and thence run along the plate 1) to the cam m, which swings the fans up edgewise by the arms which run up said cams. The plate n,with its cam m and incline 0, is attached to the sleeve q, fitted to the shaft a, and resting at thelower The plate 1) is attached to collar tof a sleeve, a, fitted on sleeve q, so as to rise and fall, and connected at its lower end to the ring v, which is attached to or rests on the upper ends of the shifting yoke 10, ar ranged to slide up and down in any suitable guideways of the shaft-box z. The sleeve (1 is fitted to the shaft a so as to turn freely on it, and has the shaft a of the equalizingwane I) attached to it, said shaft extending through the-slot c of the sleeve to, by which sleeve it turns with vane I), cam m, and plate a, but is free to rise and fall independently of them.

It will be seen that by raising sleeve to the fans will be turned edgewise to the wind all round the wheel, so that the wheel will not be turned by the wind; but when said sleeve and its plate 2 are lowered, the fans will turn sidewise, when the arms Z descend the incline 0, so that the wheel will be turned by the wind. The cam m, incline 0, and the plates at and p are relatively arranged to the regulating-vane b, so that the plate 9 is always on the side where the fans take the wind, and the plate a is on the other side.

The yoke w may be raised and lowered by hand with anysuitable cord or lever connection for the purpose; but for an automatic device to stop the wheel when the water-tank d is filled by the pump 0, worked by the wheel, and to start it when the water falls low in the tank, I connect the yoke 10 to the lever f by cords g, passing over suitable guide-pulleys, h, and suspend a bucket, z", from the end of the long arm of the lever, said lever having its fulcrum at j and a balancing-weight at k. The bucket is suspended under an overflowspout, Z, of the tank (1, through which the bucket will be filled when the tank is full. The weight of the filled bucket will force lever f down, thereby raising plate p and stopping the wheel. The bucket contains a Valve, m, which is connected by a chain, a, with the float o in the tank, said chain passing over a guide pulley, p, and lifting the valve and I00 letting the water escape from the bucket when the water falls to the low'level in the tank. The weight k will then raise up the bucket, and the plate 1) will fall and allow the vanes to turn, so as to take the wind and start the wheel. The bucket is in practice to be arranged in the well g, to be covered and protected from the weather, and to discharge the water back into the well.

By the eccentric hanging of the fans t" to the wheel-arms they regulate the speed of the wheel self-actingly, in consequence of the greater pressure on the broader sides of the fans turning them more edgewise to the wind as the force of the wind increases, so that the driving effect of the wind on them is diminished in proportion as the force of the wind is greater, thus preventing the wheel from running faster. 1

The shaft (1, is geared with the pump by the bevel-wheel t, pinion a, crank v, and the connecting-rod 10; but it may be geared in any other approved way.

Having thus described my invention,I,claim as new and desire to secure by Letters Patent 1. The cam m, plate 12, sleeve q, plate 1), sleeve a, and the regulating-vane b, in combination with the fans i, pivoted eccentrically to the arms f of the wheel, and having the trailing arms Z, substantially as described.

2. The lever f, cord g, guide-pulleys h, yoke 10, and ring 1;, in combination with the sleeve a, plate 1), and the fans i, said fans being pivoted eccentrically to the arms of the fan-wheel, and having trailing arms Z, substantially as described.
